I bought mine last April 8th. It doesnt flicker,but ive noticed its really light unless tilted a certain way. Maybe i should take it in to the pro's. Applecare is set to go into effect after the 8th of April too.

I have a 1st gen CD Macbook that suffered from screen flicker. I've had it repaired twice. The first time they replaced the inverter and the second time (3 months later) they replaced the logic board and I haven't had a problem since. I don't use the Macbook for much now that I've graduated college bc I'm always on my iMac at home...but even with it being a Core Duo it's still rockin - I've up'd the RAM to 2gb and the hard drive from 60gb to 120gb and I'm good to go. (both very easy to do in the MB)
